I've been sitting in an Ikea Marcus (not the leather one) every work day since 2016 and I find it very uncomfortable. I like the mesh back but I'm 6'2 and find it just too rigid for me. I went and tried a few cheapo Staples chairs out but didn't love them, so I think the Marcus beats those out, but I'm saving up for a more expensive chair that gives me more customisation.

I'm using Marcus for like 10 years at work. It's perfect for me, I can sit all day on it. I actually want to go to work and avoid working from home just to sit on my chair!

I know that there are better chairs that Marcus but nothing beats it for the price... It was the best 200 euros I had ever spent.

Used it for 1 year and it only got my spinal aches worse. The issue is that you tend to lean sideways in it, and leaning straight back doesn't help. Switched to Ikea's Bleckberget.

Myself and two colleagues own this and love it.
